Fire Weather Planning Forecast for Northeast Montana
National Weather Service Glasgow MT
215 PM MDT Wed Aug 13 2025

.DISCUSSION...
Most thunderstorm activity today is confined to areas south of
the Yellowstone River valley where greater instability is setting
off strong to severe thunderstorms from the Big Horns to the Black
Hills. Otherwise, closer to our region, conditions will remain dry
and calm, with maybe an errant thunderstorm wind gust sneaking
into Wibaux County from the south this evening. Some breezy to
gusty northwest winds will accompany a cool front tomorrow, but
humidity will not be nearly as dry as today.
